Collarblind: Red Scare

[Outline of the Remainder of the Series]

[A brief outline of what would have happened in the series had it continued.]

The progression of stories would have been:

Collarblind: Red Scare (Flitter/Cloudchaser, red collars)

Collarblind: Out of the Blue (Ember, blue collar)

Flash is tasked by the government with convincing Ember to join them
First chapter would have been called "Diplomatic Immunity" (because blue collars are for diplomats)

Collarblind: Silver Lining (OC, silver collar)

Flash is tasked with choosing a collar for a mare who has been in a coma since before the Fall
He decides to play a trick on her and convince her he's part of the Resistance and has come to save her from this "patriarchal hellscape" she's awoken in; hilarity ensues
First chapter would have been called "Decisions, Decisions" (because silver collars are for undecided mares)

Collarblind: Nothing Rhymes With Orange (Zecora, "orange" collar)

A joke story wherein the rhyming zebra Zecora spills orange juice on her collar and stains it orange

Collarblind: Collarless (Undecided character(s), no collars)

Flash is captured by a group of Resistance mares who are aware of his infamous exploits across the country and put on trial
Of course he escapes in the end and sells them into slavery, but briefly he gets a taste of his own medicine when they collar him

Collarblind: Blacklisted (Undecided character, silver collar)

Plot points:

Though each of the stories was a self-contained episode of Collarblind, there was a small overarching narrative for the whole series involving the two recurring characters of Crunch and Millicent
Number Cruncher ("Crunch") and Millicent, Flash's nerdy account and submissive assistant, respectively, are actually Resistance members in disguise who have taken jobs with Flash to surveil him as he works for some of the richest and most powerful masters across Equestria
Crunch's black arrow cutie mark doesn't represent the "black arrow of profit," it represents his proficiency with a bow and arrow; he's actually a highly-trained marksman
Millicent is only pretending to be a naive idiot; in reality she's a very intelligent manipulator who subtly guides Flash to do what she wants a la Keyser Soze (she lets slip her true intellect by accident a few times, for example when she reveals she has read the books of Manechiavelli, but Flash is too arrogant and foolish to notice)
The ending of the story ideally would have been that Millicent revealed herself as the hidden genius she was and worked with Crunch to kill Flash once his usefulness had run out
The final scene of the series would have been Flash, mortally wounded, lying on the floor laughing in stunned horror as he realizes his ditzy assistant outwitted him in the end
